More work on Kuliel's jump.
I thought that I had nailed this down before, but now that I'm mostly working in Firefox the jumping issue is back.  I think he was getting stuck in the floor - he would jump fine once, then not any more (sometimes bumping into the player would fix it; not sure why.)  I made him jump up a bit instantaneously to fix this, and then velocity jumping kicks in.  It seems to work in FF and Chrome now.
